No, what’s silly is to not follow the correct grammar of spelling out an acronym in full the first time. Microsoft does this all the time and you’re left not being able to use the document because you have no idea what they’re talking about, and they haven’t linked to anything about it either. e.g. try Googling COM and let me know how you go with finding out what it means. You should never assume the reader knows what it is. It’s gate-keeping.
